[sdiy] 4016 versus 4066 switches in MemoryMoog

[Jarno Verhoeven]

4016 has a higher on resistance, 4066 lower, but they are both switching audio signals, hmmm.Is the extension on both the same (do these come in buffered and unbuffered?)?

Onderwerp: [sdiy] 4016 versus 4066 switches in MemoryMoog 

Hi all,

I've been reading the MemoryMoog schematics, and I notice that in certain parts of the voice card they use 4016 analog switches (for example, turning osc waveforms on and off) but in other places they used 4066 analog switches (for example, voice modulation enables).

http://www.memorymoog.com/docs/mm_schematics.pdf

I've always regarded these two chips as broadly equivalent, but apparently Moog didn't think so. What's the important difference between them, and why use one rather than the other?

Thanks,
Tom
